The city of San Jose is spread over a huge area (a good fraction of Santa Clara Valley aka Silicon Valley). The downtown area of San Jose which you might think of as a city is rather small.
The convex hull of San Jose also encloses a ton of junk that is not San Jose because of their unincorporated enclaves and incorporated exclaves. San Jose badly fails my test of whether a city is good or bad based on the geometric complexity of their boundary.
